We got our first meat rabbits last janurary and I ended up buying an unrelated buck and doe from the same breeder. The breeder kindly put the doe in with a different buck so she would have a litter unrelated to the buck we bought at no extra cost.
This was great as we could see how it went, experience her pregnancy and birth and if we decided to keep any does in the litter we knew they would be unrelated to our buck.
However! It was the does first litter, she gave birth to two kits but chewed the feet off them as i believe they were stuck. I kept an eye on her and two days later her vulva still did not look right so my husband and I bought her inside and took a proper look, she had another kit stuck which we had to help her deliver.
She has since gone on to deliver two more litters of three kits. I was hoping for larger litters but it doesnt matter too much.
So i think there are pros and cons to different things, if the doe had already had a litter with the breeder we might have avoided losing our first litter. On the other hand, it was great (not for the doe, bless her!) experience and we learnt a lot.
When I get another doe I will get one that is ready to breed. The way I see it, buying a kit would cost money to grow on and also time, all the time its maturing, its not breeding.
It's a shame you are not closer as i have been thinking about trying a NZ white.
